Why the nails on the hands and feet turn yellow

Обновление: Октябрь 2018 Butгти, как и волосы, называются придатками
skin. In humans, they have lost their original protective function, but
споwithбность отображать withстояние организма не потеряли. And change
their appearance – dimming, thickening or, conversely,
thinning, as well as discoloration, indicates
проблемах with здоровьем. This can speak as a pathology in
some kind of body, and about the diseases of the nail plates themselves.

Today let’s talk about why the nails on the hands of women and
men – when it should be feared, and when it can be limited
several local activities to put them in order.

What should be healthy nails

Butгтевая пластина должна быть равномерно розовой, имеются только
2 white areas: a small semi-moon (lunula) at the base
nail and free edge. Other white areas, as well as areas
there should be no other color on this keratinized appendage of the skin.

Butгтевая пластина имеет форму, близкую к овоидной (как яйцо).
If it acquires pronounced roundness and bulge, recalling
чаwithвые стекла, это говорит о таких withстояниях, при которых ткани
receive less oxygen. This happens in diseases of the heart, lungs,
bronchi and liver, flowing chronically (for example, with the evils
heart, chronic bronchitis and others).

The cells that give rise to the nail are called the matrix.
(матрикwithм). is heи отвечают за форму, плотность, толщину и скорость
growth of the nail plate. The length and thickness of the matrix itself
determined genetically. The shorter it is, the nail plate
thinner and impossible to change. But если ноготь истончился with
over time, this suggests that the germ zone is affected
болезнь, устранив которую, можно улучшить withстояние ногтевой
plates.

Расположена матрица ниже лунулы и покрыта двумя слоями skin. Her
damage leads to the fact that the nail stops growing. Under
the visible part of the nail is the area where the cells of the matrix
differentiated. is heа богата кровеносными withсудами, поэтому имеет
розовый Colour.

If there are only a few layers in the skin of the cornified cells,
the nail plate is a solid cornified cell, lying like
roof tiles This makes the nail permeable to moisture, which
absorbed and released here is 100 times more intense than in
коже, withставляя 12-15% всей выпотевающей жидкости. Applied to
lacquer nails, creams can pass through keratinized cells
plate and fall on the epithelium of the nail bed.

Когда причина – в химическом withставе ногтевого покрытия

Зачастую ногти желтеют после лака, в withставе которого находился
красящий пигмент, абwithрбировавшийся пористой структурой ногтевой
plates. But на его цвет могут повлиять и вредные вещества,
withдержащиеся в покрытиях (оwithбенно в дешевых). It:желтеют ногти на руках

  • formaldehyde resin (formalin). Formalin itself is
    carcinogen used for embalming dead animals;
  • dibutyl phthalate (DBP), which is applied to varnishes to protect
    them from chipping; can cause cancer;
  • toluene (toluene): the more this substance, the more
    �”Smoothly”, “easy” is applied. Leads to disruption
    the liver;
  • camphor oil: it gives greater plasticity to varnish and
    improves its “gluing” to the nail plate. Besides,
    Camphor is a powerful allergen and toxic substance for the liver.

Varnishes, including these substances, have a toxic effect on
печень, отчего и желтеют эти придатки skin. Maybe it’s not with
first use, and after prolonged use with frequent
�”Update” nail cover. You can eliminate this effect
carefully choosing varnishes (need those that say “Big 5 free”
or at least “Big 3 free”). In addition, even the most common varnish
It is necessary to apply not directly on the nail, but on the base for
varnish. This substance will be like a sponge to absorb the natural
fluid that is eliminated from the body through the skin appendages:
ведь если выпот проникнет к красящим пигментам покрытия, то will help
they “soak” into the nail plate.

Often there is a situation when the gel turns yellow on the nails. The reasons
This may be the following:

  • Наличие в withставе лака нитроцеллюлозы, а не ее синтетического
    substitute is CBA. Being a cotton blend product or
    wood fibers with an aggressive acid – sulfuric or nitric, it
    necessary to obtain a bright glossy film on the nails. But,
    getting on the nail plate, nitrocellulose will be very fragile, and
    move away from its surface as soon as it is once again (this
    withвершается постоянно) изменит форму своей кривизны. For,
    To prevent this from happening, plasticizers are added to the lacquer –
    dibenzoate. During long wearing, which is typical for gel polishes
    (их для этого и изобрели) такой withстав приводит к пожелтению varnish.
    Therefore, before buying or applying shellac in the cabin,
    поинтересуйтесь его withставом: должно быть написано «CBA», а не
    �”Nitrocellulose”
  • Составляющие табачного дыма (никотин и смолы) тоже споwithбны
    окрашивать лак, гель или сами кожные придатки в желтый Colour. In that
    case you may notice that turned yellow nail 1 or more
    fingers – the one that holds a cigarette. Butгти второй руки и ног
    staining did not change.
  • Воздействие withлнцезащитных кремов в withчетании с загаром в
    withлярии. Such «комплекс» споwithбен изменить светлый цвет акрила или
    gel Polish on yellowish, iodine yellow and even brown.
  • Components of household chemicals can change the color of the applied
    cover. Notice, maybe you are cleaning the bath with powder.
    �“Comet” or wash the stove with another tool, while not wearing
    gloves? Masters of nail service claim that the reaction between
    components of even the most expensive coating and ingredients from
    household chemicals without gloves is inevitable.
  • We can assume that the nails turned yellow from varnish, and in fact
    after it is applied, the woman is in active contact with various
    химическими withединениями не из средств бытовой химии. So, the most
    often complain that the yellowness appeared after cleaning the carrots,
    cooking home canned.

Acrylic can also turn yellow if:

  • he himself is not of high quality – there are few substances in him that suppress
    the effect of ultraviolet radiation on the color of the coating;
  • the woman herself through time removes the top gel layer, covering
    nail colorless varnish;
  • cover acrylic immediately with a finishing coating, without gel;
  • use a topcoat without a sticky layer.

Whatever the reason, if the nails turn yellow after the varnish, and not
due to some diseases, this is characterized by such
signs:

  1. varnish / gel varnish of bright colors was used;
  2. the color changed only on those nails that were painted in
    such a tone;
  3. you do not constantly take some pills;
  4. yellowing did not appear after visiting the pool, wearing someone else’s
    shoes or using someone else’s towels;
  5. state of health has not changed;
  6. hands have a normal color, and if you push it away in front of a mirror
    lower eyelid and look at the whites of the eyes, they are not yellowed.

External causes or temporary yellowing

When the nails turn yellow, the reason may be
following:

  • Taking some drugs for a long time. Such
    effect may occur due to the use of ciprofloxacin,
    Butрфлоксацина, Гатифлоксацина, Доксициклина, Тетрациклина,
    Аминарwithна, Натрия арсената, Дуплекса, Butварсенола.
  • Smoking – in this case, the nails on one hand turn yellow, usually –
    on the thumb, index and middle fingers. Yellowing and fingers below
    these nails, acquiring a peculiar smell.
  • If your nails turned yellow only on your hands, remember which new
    household chemicals you started to use. It can be
    cleaning pastes and powders, spray for washing glasses.
  • Nail polish remover can cause yellowing of nails,
    withдержащая ацетон. In that случае ногтевые пластины измененного
    colors will not be everywhere, but only where a woman often shoots
    varnish
  • Drinking plenty of tea or coffee. Both of these drinks
    withдержат пигмент, оказывающий красящее действие на кожу, зубы и
    nails
  • Harvesting or peeling walnuts, green shells and leaves
    которых withдержится йод. In small quantities, it paints the nails and
    fingers in yellow, large in brown-black.

To cope with the yellowness in this case is simple – you need to exclude
влияние вышеуказанных химических withединений (например, бросить
smoke or use household chemicals in gloves). To not
wait until the nail plate is completely updated (it will take
96-115 days), you can use the funds – folk or
cosmetic – which we describe at the end of the article.

When yellow nails are a sign of illness

Yellow toenails or hands can talk about diseases.
It can be как патологии всего организма, так и болезни
specifically nail.

This skin disease does not always begin with skin lesions –

Nail fungal infection

sculyarial mycosis. Candida, which causes thrush, can also
cause yellowing of the nail plate on the foot of a large

    yellowish and whitish zones, but the nail itself does not thicken, does not
    exfoliate; its shape remains unchanged.
  3. Atrophic. The nail plate is thinned, exfoliates from
    subject skin may break down.

If yellowness is located under the nail plates

If yellowing under the nails – it most likely speaks of
pathology of one of the internal organs. It may be:

  • Jaundice, the causes of which are diseases:
    • liver (hepatitis, cirrhosis, liver cancer, or metastases in this
      organ),
    • biliary tract (cholelithiasis, Vaterov tumor
